' 4 claims. (C1. 263-126) Y The invention relates to window regulatorsand has for one of its objects the provision `vof means for raising andlowering inner and outer Windows so constructed that the means forraising and lowering the outer window may be made` inoperative fromoutside the vehicle to permit raising the outer window so that thevouter side of the inner Window may be washed. Another object is toprovide an improved guide for normally maintaining the rack oi the lwinvdow regulator in engagement with its driving pinion; With these as wellas other objects` in View, the invention further resides in the novelfeatures oi construction and combinations and 1 arrangements of parts asare more ully hereinafter set forth.

In the drawing:-

Figure 1 is an interior sidey eievation,'partly broken away, of aportion of a vehicle to which our invention is applied;

Figures 2, 3 `and 4 are cross sections on the lines 22, 3 3 and 4 4,respectively, of Figure 1;

Figure 5 is a cross section on the line 5 5 of Figure 2.

`Our invention is designed particularly for use in railway cars and asshown is applied to a Pullman car, 'the side Walls of which have pairsof adjacent window openings 1 with the chambers 2 between the pairs.formed by the uprights 3 at the edges of the openings and the inner andouter panels 4 and 5, respectively. The inner and outer panels also formwith the uprights chambers 6v to one side of the openings, which areadapted to receive the inner and outer windows I and 8, respectively,when raised.

Separate window regulators are provided for operating the windows 7 and8, each of these regulators'comprising the lifter arm 9, the rack 19,the pinion '11 for driving the rack, the handie 12 and suitableirreversible drive mechanism 13 between the handle and the pinion. Thelifter armi? extends within both chambers 2 and 6 and is pivotallyconnected intermediate its ends to the bracket 14, which is mounted uponan upright 3. lThe free end of the lifter arm is connected in the usualmanner to the window while its other end is pivotally connected to ,50the upper end of the rack 10, which extends within the chamber 2. Thepinion 11 is also mounted within this latter chamber. Y

To provide for washingthe outer side of-th inner window without thenecessity of operating the window regulator for the outer window, we

These chambers arel have provided means operabler from outside the carfor making the window regulator for the outer window inoperative tothereby release the outer window so that the workman may raise the sameand have access tothe outer side of the inner window. In detail, thepinion 11 is xedly mountedupon the shaft 15 and in the present instancerthe two are integral. This shaft extends within the chamber 2 and hassecured to through an opening in the outer panel r5. The shaft 15 isslidably mounted in the bearing 17 which is secured to the partition 18extending vertically within the chamber 2 between its side walls. Fordriving the pinion from the irre- Versible drive mechanisml 13, we haveprovided the bifurcated driving member 19 and the cooperating bifurcateddriven member 20, both being preferably formed of sheet metal. Thedriving member 19 is iixedly secured to the driven member 21 of theirreversible drive mechanism,

while the-driven member 20 vis fixedly secured to the inner end of theshaft 15. To maintain the alignment of these members, the driven member21 of the irreversible drive mechanism has the pin 22,the outer end ofwhich' is engageable in the axial bore 23 in the inner end portion ofthe shaft 15. There is also the sleeve 24 which is fixed upon the innerend portion of the shaft 15 and has a bearing in the partitionv 25within the chamber 2 and extending parallel to the partition 18. Fornormally maintaining the pinion 11 in engagement with the-rack 10,

we have provided the coil spring 26, which is located between the basesof the driving and driven members 19 and 20 and yieldably holds theshaft 15 and consequently the pinion 11 in its outermost position, whichis determined by the bearing 17 engaging the outer side of the pinion.The driving and driven members 19 and 20 are arranged to permitlongitudinal movement of the shaft 15 and associated parts a sufiicientdistance to disengage the pinion 11 from the rack 10, this beingaccomplished bythe workman pressing upon the push button 16. While thispinion is held out of engagement with the rack the outer window may beraised to permit washing of the outer side of the inner window.

' For the purpose of guiding the racks 10 so that 1,05

they will be held in mesh with the driving pinions, regardless of ytheangularity which the racks as- VVsume While operating the windows, Wehave pro-A soV its outer end the pair of spaced rolls 28, which engagethe plain edge of the rack. These rolls, as shown, are mounted upon therivets 29 secured to and extending transversely of the outer end of eachframe and suitable Washers 3Q are also secured upon these rivets toextend at the side of the rack opposite that adjacent the frame. In theWindow regulator for operating the outer Window, the frame 27 isjournaled upon the bearing 17, as shown particularly in Figure 2, whilein the Window regulator for operating the inner Window, the frame 27 isjournaled upon the sleeve 3l which surrounds the outer end portion oithe shaft 32, the driving pinion for the rack occupying the inner endportion of this shaft. This shaft is directly secured to the drivenmember of the irreversible drive mechanism and is also journaled in thepartition 18.

From the above description, it will be seen that We have provided awindow regulator construction which permits a Workman outside the carmaking inoperative the window regulator for operating the outer WindowAso that he may raise this outer Window to have access to the outer sideof the inner Window. It Will also be seen that we have provided animproved means for guiding the racks of the window regulators and thatthe guide -for the Window regulator operating the outer Window ispivotally mounted upon a bearing for the driving pinion shaft, which isoperable to disengage the driving pinion from the rack.

yWhat we claim as our invention is:

1. The combination With a vehicle having a window opening and a Windowfor the opening, of a Window regulator for operating the Window, saidWindow regulator including a handle at the inside of the vehicle,apinion operatively connected to said handle, a rack, a spring fornormally holding said pinion inengagement with said rack, and a memberoperable from outside the vehicle for axially moving said pinion againstthe eiort exerted by said spring to disengage said pinion from saidrack.

2. The combination With a vehicle having a Window opening and a Windowfor the opening, of a Window regulator for operating the window,including a handle at .the inside Vof the vehicle, a pinion operativelyconnected to said handle, a longitudinally movablefshaft carrying saidpinion and operable for longitudinal movement from -outside the vehicle,a rack, a guide for.the rack pivoted `concentric With said shaft, andmeans for yieldably holding said pinion in engagement with said rack.

3. The combination with a vehicle having a Window opening and a Windowfor the opening, of a Window regulator for operating the Window having ahandle at the insideV of the vehicle, a rack, a pinion, yieldable meansfor normally holding said pinion in engagement with said rack, anirreversible drive connection between said pinion and handle, and meansoperable from outside the vehicle for moving said pinion against theaction of said spring to disengage the same from said rack.
